Plywood is a kind of board made by planing or rotary cutting trees, cutting them into veneers and pressing them on the base.
Plywood is mainly used in building construction. It has light weight and good flexibility on the outer surface of modeling, such as arc-shaped places. Plywood is commonly used in building, which generally has 7, 8 and 9 floors. The thickness of one floor is 1 mm, and the veneer of each floor is 90, which not only increases the strength, but also reduces the deformation.
Dense density board is made of small diameter wood with branches or other plants with high fiber content, which are pulped into fibers and mixed and pressed with glue.
Density board is made of sawdust and sawdust by hot pressing with glue, and it is divided into high density board and medium density board according to the amount and density of sawdust inside.
